Comparative StudySimultaneous combined anterior and posterior surgery for severe thoracolumbar fracture dislocations.
To analyze the clinical results of simultaneously combined anterior and posterior surgery for severe thoracolumbar fracture dislocations, and to clarify the surgical indications for these high-energy injuries. ⋯ For severe thoracolumbar fracture dislocations that cannot be effectively treated with either an anterior or posterior approach alone, simultaneously combined anterior and posterior surgery is a reliable method that can achieve a sufficient decompression, reduction and reconstruction.

Comparative StudyPosterior pedicle screws combined with shortening and release techniques for lumbar and thoracolumbar adolescent idiopathic scoliosis.
To prospectively evaluate the clinical and radiographic effects of posterior surgery with wide posterior shortening release and segmental pedicle screws techniques in a consecutive group of patients with thoracolumbar /lumbar adolescent idiopathic scoliosis. ⋯ Wide posterior release and segmental pedicle screw instrumentation has excellent radiographic and clinical results with minimal complications.

Comparative StudyAnalysis of the relationship between morphology of intervertebral disc and some correlated factors following discography in patients with chronic low back pain.
To evaluate the diagnostic effectiveness of discography in discogenic low back pain (LBP). ⋯ (i) Compared with the younger patients, older LBP patients have a lower positive rate of discography despite the presence of more serious degenerative disc changes; (ii) outer layer disruption of the annulus fibrous correlates with positive discography; (iii) MRI intensity changes are not specific in diagnosing discogenic pain. Additional discography is needed to identify the painful disc; and (iv) the contrast volume injected into discs can be affected by a variety of factors which restrict its diagnostic value.
